MySQL和Rails Server的問題

Question

最終編輯：我玩了幾個不同的文件，但出現了更多錯誤，然后從頭開始重新安裝了rvm和其他所有內容，找到了一些修復程序並對其進行了編輯，最后一切正常。 謝謝你們每一個人的幫助

編輯：我注意到它說庫未加載：/usr/local/mysql-5.5.10-osx10.6-x86_64/lib/libmysqlclient.18.dylib（LoadError）

但是我有mysql 5.5.11，我該如何解決？

我確實搜索了過去3個小時，但沒有發現任何有效的方法

當我嘗試啟動服務器或生成模型時，也會發生相同的錯誤

我有捆綁器和mysql2 gems。

生成器（2.1.2）捆綁程序（1.0.12）erubis（2.6.6）i18n（0.5.0）郵件（2.2.17）MIME類型（1.16）mysql2（0.2.7）

我得到以下輸出：

Answer 1

每當遇到加載錯誤時，都應確保已安裝並安裝了所有依賴項。

1. 確保您的Gemfile中有gem mysql2 。
2. 如果您尚未在gem install bundler安裝bundler，請進行gem install bundler 。
3. 運行bundle （與bundle install相同）。

然后嘗試再次運行服務器。

Answer 2

帶有Rails 3.0.3的mysql2給出了一些錯誤，因此請嘗試使用3.0.6更新Rails版本

它工作正常，所以嘗試
